Scanning Systems for Searching Double Strangeness Nuclei in Nuclear Emulsion

Scanning systems for detecting double Lambda hypernucler events in nuclear emulsion plates with high statistics are presented. The systems are complexes of optical microscopes and computers to provide fast emulsion scanning and image recognition for vertex-like objects. We recently introduced a two-stage process of vertex detection to exclude misdetected objects. The method can be expected to reduce conventional eye-check works and increase search speed for double Lambda hypernuclear event.
